我不能maven安裝我的空maven項目

Question

我試圖做一個api。我想嘗試使用Intellij Idea的Spring來實現Hibernate &，我從來沒有使用它們。

我已成功使用intellij創建Spring項目。但即使該項目是'空'，我還沒有改變任何東西，我不能做一個maven安裝它。

也許我需要某種的地方屬性，但我不知道哪些和在哪裏把它們...

Answer 1

我發現是什麼問題！

所以就是因爲我沒有像你說的那樣配置一些東西。我沒有需要安裝的jdbc（我不知道爲什麼，我並不需要它），但只是把對文件的一些屬性：/main/ressources/application.properties

spring.jpa.database=POSTGRESQL 
spring.datasource.platform=postgres 
spring.jpa.show-sql=true 
spring.jpa.hibernate.ddl-auto=create-drop 
spring.database.driverClassName=org.postgresql.Driver 
spring.datasource.url=jdbc:postgresql://localhost:5432/mybase 
spring.datasource.username=username 
spring.datasource.password=mdp 

THX爲無論如何答案:)

Answer 2

你缺少你的類路徑DB JAR如果你正在使用Maven的 /搖籃，只是包括JDBC驅動程序d依賴於你的POM/gradle 文件。

從這裏摘自： Spring Boot: Unable to configure

至於第一次嘗試的依賴添加到您的POM：

<!-- ORACLE database driver --> 
    <dependency> 
     <groupId>com.oracle</groupId> 
     <artifactId>ojdbc6</artifactId> 
     <version>11.2.0</version> 
    </dependency> 

那麼，如果它不工作與「MVN手動添加安裝：安裝「文件」的目標..
